Ecotype vs. Ecophene

Ecotypenoun

(ecology) A phenotype that is adapted to a specific environment.

Ecotype

In evolutionary ecology, an ecotype, sometimes called ecospecies, describes a genetically distinct geographic variety, population, or race within a species, which is genotypically adapted to specific environmental conditions. Typically, though ecotypes exhibit phenotypic differences (such as in morphology or physiology) stemming from environmental heterogeneity, they are capable of interbreeding with other geographically adjacent ecotypes without loss of fertility or vigor.

Ecophenenoun

The range of phenotypes produced by a genotype in a particular habitat
